Boost Numbers on Early 99

[AlaskanEngineer]

Alright, I have a mostly stock Early 99 and I am just wondering what is typical boost numbers when pushing real hard while towing in an 80 HP tow tune (ie I am using DP tuner).

See sig for truck details, as I said its pretty much stock...

NOTICE THE LACK OF ANY EXHAUST MODS... You will soon see thread asking about these... wondering though if I could be limiting my boost because of this...

I normally see around 20 psi in any tune but my 120 race, which can give me 24.

stock I saw 16-18 psi bone stock

with my tow files I see 24-26 with 4" exh and afe stage II

on the extreme I can see 28-30 but its out of it map .. so it is a waste

this is in my early 99

I can pull 25-27 psi no sweat in 80e. If I keep on it, I can hit 30. Stock turbo, stock sticks, wastegate tightened up all the way but red line still plugged in.

superduty4x4, I am unfamiliar with what you said about wastegate being tightened up all the way... I have heard of unplugging the red line but just have no interest in overboosting... Can you elaborate on your wastegate?

Stock I saw about 15-16 PSI

80e I see around 20 maybe 21 tops

120 race, see 20 easy, usually works up to 22-24.

My boost gauge is mechanical and plugged into the map line with the t fitting.

You remove the wastegate controller gizmo from the turbo (2 10mm nuts and an E-clip on the turbo... be careful not to loose that clip!), and twist the fitting down as tight as you can get it. Once you look at it, you'll see exactly what I'm talking about.
I'm thinking of opening mine up a little bit now... can't afford a new turbo

I have a little Striker 2 65hp module on mine and it will jump to 20 real quick and then I'll get an over boost CEL and it will defuel and slow me down. How do I fix that again???
